I wouldnt completley shut him down but your right, he really sucks right now.
What Frank is doing right now is actually good. He starts Yi, he plays the first few minutes and if he shoots well he stays in. But on most nights, Yi takes himself out (dumb fouls) so its basically him coming off the bench.

I do think Ryan Anderson should get some more minutes though. I dont like Bobby Simmons playing PF, thats basically why we are getting out rebounded every game. Though it has somewhat worked the last few games because Bobby can shoot the 3 fairly and since our team relies on 3's so much, it works.

Honestly, playoff hopes this year seem very dismal. So the rookies that need game time to develop should be playing a LOT in the final stretch. Young players dont develop by sitting on the bench, afterall.

I'm not saying we should "tank" at this point. But if the season is lost, why not give the rookies more minutes? Whats the worst that could happen... improved lottery chances?
